The solution for given system of equations is: x = 6 and y = 3

Or

(6,3)

Step-by-step explanation:

Given equations are:

There are three methods to solve simultaneous equations

We will use the elimination method as the coefficients of x in both equations are already same

Subtracting equation 2 from equation 1

Putting y = 3 in equation 2

Hence,

The solution for given system of equations is: x = 6 and y = 3

Or

(6,3)

(x+3)(x+7)

step-by-step explanation:

y > 1/3x

y < = -x + 4
